Existing motor positive and inverse control is generally used for vulnerabilities scan, is switched by switchings such as circuit control breakers
Switching, to realize motor positive and inverse, but for high pressure field, power of motor is larger, and general positive and negative rotation control is difficult
To be applicable in, also there is very high requirement for hardware configuration and electrical design, the present invention provides a kind of high voltage control cabinets, pass through
Two different connection relations are arranged in conductor between input terminal and switch, and three-phase electricity is realized in conjunction with the switching of three-phase disconnecting link
The positive and negative rotation control of motor is realized in the change in source, simple in structure, easy to operate.According to the structure progress to high-tension switch cabinet
A specific embodiment applied on wind turbine can be given below there are many embodiment in different transformation, the present invention.
As shown in Figure 1, in figure 1 be manual-operating mechanism, 2 be current transformer, and 3 be pillar, and 5 be pillar, and 6 be leading-out terminal
Cable, 7 be double-throw disconnecting switch (three-phase disconnecting link), and 8 be pull rod.Fig. 2 is the practical structures schematic diagram of the embodiment, and 4 are in figure
Conductor (including conductor 41-46), in the present embodiment, the output end (i.e. three-phase input terminal) of current transformer is connected by conductor
The upper moving contact 11 of double-throw disconnecting switch, while three-phase input terminal also connects the lower moving contact of double-throw disconnecting switch by conductor
12, double-throw disconnecting switch further includes static contact, and static contact is arranged between two moving contacts, and static contact connects three-phase leading-out terminal.
Upper moving contact 11, static contact and lower moving contact 12 are respectively arranged with A, B, C three-phase binding post, and insulator is provided on binding post.
A, B, C three-phase of three-phase input terminal are correspondingly connected with A, B, C three-phase of moving contact, the i.e. A of three-phase input terminal
The A phases of upper moving contact 11 are mutually connected by conductor 41, the B phases of three-phase input terminal connect the B of upper moving contact 11 by conductor 42
Phase, the C phases of three-phase input terminal connect the C phases of upper moving contact 11 by conductor 43；A, B, C three-phase of three-phase input terminal simultaneously
Being correspondingly connected with C, B, A three-phase of lower moving contact, i.e. the A phases of three-phase input terminal connect the C phases of lower moving contact 12 by conductor 44,
